【Abstract】 According to the two-dimensional edge detection algorithm, this paper proposes a three-dimensional edge detection algorithm suitable for the casting process. After the flow field data of the casting numerical calculation is preprocessed, the flow front of the molten metal is extracted by this algorithm, and the automatic extraction of the leading edge position of the molten metal and the display of the result are realized. The extraction results facilitate the process researchers to observe the position of the metal liquid front when filling, and improve the accuracy of the process analysis.更多还原
